--- Comment #8 from Martin Liška <marxin at gcc dot> ---
I've just used gcc110 and gcc112 machine (ppc64 and ppc64le) and both print
following stack-trace in the tsan error:

    #0 memset
    #1 __GI___pthread_mutex_init <null> (
    #2 Thread1 c-c++-common/tsan/race_on_mutex.c:12

I also verified that non-sanitized version in gdb also has missing source file
for the __GI___pthread_mutex_init function. Thus '<null>' is here proper value.

Can you seurer test the problematic ppc64 machine where you see:
#1 <null> <null>

What do you see in gdb if you put a breakpoint to memset function?
